Micropurge Portable 45mm Pump
The all-new Sample Pro Portable MicroPurge Pump is the first pump developed specifically to bring the advantages of low-flow sampling to sites requiring portable pumps. The Sample Pro Pump is not only able to deliver consistent low-flow rates, easy to disassemble without tools, simple to clean, and truly field rugged. Unlike other portable pumps, it is cool-running and can be operated by a lightweight backpack controller. There are no high speed rotating parts, no sample or motor heating, no costly maintenance or special generators. Sample Pro reliability and low maintenance make it more economical. Its bayonet-type twist open design makes it easy to change the pull-off, disposable bladder in seconds. The compact 14.75" unit fits in a pail for pumping and cleaning. Sample Pro innovations don't stop there. The pump is available with conventional compression fittings for tubing connections, or with a"no fitting" push-in head that's perfect for applications where the tubing is discarded frequently. Sample Pro value and rugged, all-stainless construction will stand up to tough portable use. The simple yet effective design avoids the high maintenance expenses and destructive failure modes of other pumps. Compact, rugged, and reliable, this is the first pump designed for low-flow operation inportable sampling applications.
Sample Pro Portable MicroPurge Pump
The Sample Pro Portable MicroPurge PumpThe Sample Pro Portable MicroPurge Pump uses a quick-change, one-piece bladder design. Compressed gas squeezes the outside of the bladder to force liquid out of the pump; there is no gas contact with the pumped water inside the bladder. Squeeze type bladder pumps are supported by years of independent research that shows they provide unaltered samples for even the most sensitive parameters.
Water enters the pump through the inlet in the upper, head section, then flows down into the bladder. The high inlet helps keep the pump fromclogging if it is accidentally lowered into a sediment-filled sump.
Check valves with stainless steel seats and Teflon check balls are located at the inlet and outlet. A replaceable inlet screen is provided for wells with high solids levels to help ensure proper sealing of the check valves. The Sample Pro Pump is shipped in a heavy-duty tube with rubber end caps to help keep the pump clean and protected between uses.
The pump is disassembled by a 1/4 turn of the cap and body; no tools are needed. The bladder pulls off for replacement. Both check valves are press-in, pull-out design, and usethe same size Teflon check ball.
Compression-type and push-in tube fitting kits are available and can be used interchangeably. Both options provide high pull-out strength, but a cable eye is also included for applications where a support cable is desired.
